FAQ:
Q: What is a 12V DC power supply?
A: The 12V DC power supply is one of the most commonly used power sources today. These are switch mode power supplies which means the output is regulated to 12V. Generally, the 12VDC output is obtained from 110VAC or 220VAC inputs using a combination of transformers, diodes and transistors. Most LCD screens, hard drives, audio devices and other device needs them to work together.
Q: What is the best power inverter for a car?
A: The best power inverter for cars is the KRIËGER 1500 Watt 12V Power Inverter, which has a dual 110V AC outlet and is MET approved according to UL and CSA.
Q: What is DC DC power supply?
A: A DC-to-DC power supply converts a direct current (DC) input supply to a DC output supply typically at a different voltage level. Many types of DC-to-DC converters are available and are grouped into three categories: linear, switching, and switching flyback.
Q: What is an universal power supply adapter?
A: Universal power adapters are devices that make it possible to connect a power supply to various devices in just about any setting. There are adapters for handheld devices, laptops, and even for various types of household appliances.
